My phone connects to wifi well. But when I go out, I can't get 4G. When mobile data is turned on, it only shows E... before upgrading or updating the phone it still works fine.
Does anyone have similar problems?
Do you have any way to fix it?
I have tried many different solutions but still have the same problem
Thanks!
